to ask how your four year old behaves in a restaurant?

[AliBean]

I am wondering if the way I expect my DC to behave is unreasonable. ..or old fashioned... are children allowed to crawl on the floor, climb on the furniture, race around in a restaurant?? And if this behaviour is in fact as unacceptable as I think it is, how do their parents achieve the ability to NOT CARE and enjoy their meal without copious amounts of wine and/or earplugs?
Perhaps I am a boring mean mummy but having met with friends for lunch today I remain gobsmacked by how they let their children behave..my DC1 kept getting sucked in but I kept intervening and I ended up feeling like I was the only one who cared and went home feeling really stressed but wondering if I am expecting too much and that's how all 4 year olds behave?

mother yes, we had a period of about 3 years where we only went out for meals when absolutely necessary which was difficult as me and DH used to dine out regularly pre-DC and no babysitters meant we couldn't go out by ourselves either.

Even now, we don't feel able to go out to proper posh restaurants so we generally eat poor food just because the venue is more child-friendly
